Is program verified if "lock entire chip from readback" is checked?

We have a factory in Hong Kong building and programming nRF51822 modules for us. We may go to a fancier solution in the future, but right now we are using nRFgo Studio and a bed of nails fixture to program the modules.

They are programming them with the "Lock entire chip from readback" option checked, and they asked me to verify that the programmed firmware is verified if this option is checked. I assume so, but I wasn't sure. Can anyone at Nordic confirm that the verify step happens before the UICR register is written to lock the chip?

Thanks, Philip
